Here, the electron exposure time is set at least more than 2 times of situation of low frequency illumination period by explanation.In order to simplify It is bright, the electron exposure time is set to low frequency illumination period 4 times of the 2T seconds of T/2 seconds.

In the case, 1 shown in luminance signal obtained in infomation detection processing by optical pattern test section 141 schemes Piece becomes, following picture P100.

Fig. 9 is the figure for the picture P100 for being shown as an example.Moreover, in picture P100, actually display that by The image of body is taken the photograph, still, for convenience of description, the image of subject is not shown.

In fig.9, shown on the right side of picture P100, in the case where the vertical direction of picture P100 is set to the time Cycle be T/2 seconds illumination light light quantity change.

Here, optical pattern test section 141, will be part more than setting with the light quantity of illumination light in picture P100 Corresponding region is set as judging region.It is the region for detection information to judge region.

In the case where the electron exposure time is k (more than 2 integers) times of low frequency illumination period, in picture P100, Setting k judges region.In k judges region, vertical direction each adjacent two judge region at intervals of certain.

For example, in the case where k is 4, in picture P100, such as Fig. 9, setting judge region R10.1,10.2,10.3, 10.4.Hereinafter, each of region R10.1,10.2,10.3,10.4 be will determine that, also simply token is to judge region R10.

Moreover, for example, in the case where the electron exposure time is 8 times of low frequency illumination period, in picture P100, set 8 judge region.

Here, picture P100 is set to, information is not overlapped in picture during illumination light.

In the case, each judgement region R10 is high-brightness region.Here, high-brightness region is, the judgement region The average value of the brightness value of multiple pixels in R10 is region more than defined judgment threshold.That is, high-brightness region It is bright region.Here, judgment threshold is, the threshold value for detection information.

Hereinafter, it will determine that judgement region for being averagely less than judgment threshold of the brightness value of multiple pixels in region, claim For low brightness area.

In information overlap in the case of illumination light, each judgement region R10 in picture P100 is, high-brightness region or Low brightness area.In the case, picture P100 is shown, certain light and shade pattern.

Herein, it is contemplated that, high-brightness region is defined as " 0 ", low brightness area is defined as " 1 ".In the case, light figure Sample test section 141, the average value of brightness value by judging multiple pixels in each judgement region R10 in picture P100 are No is more than judgment threshold, so as to detect " 0 ", " 1 ".That is, optical pattern test section 141, with least the two of picture P100 Row unit more than a, detection are overlapped in the information of illumination light.

That is, optical pattern test section 141, the state of multiple brightness values corresponding with picture P100 is detected as bright Dark pattern, so as to detect the information for being overlapped in illumination light.Each brightness value is the value obtained from signal of video signal.That is, Optical pattern test section 141, by detecting light and shade pattern from signal of video signal, so as to detect the information for being overlapped in illumination light.

Herein, it is contemplated that, for example, the indication code " 1000 " as configured information is overlapped in illumination light.In the case, picture Judgement region R10.1,10.2,10.3,10.4 in P100, be respectively low brightness area, high-brightness region, high-brightness region with And high-brightness region.

In the case, optical pattern test section 141 is more in each judgement region R10 in picture P100 by judging Whether the average value of the brightness value of a pixel is higher than judgment threshold, so as to detect indication code " 1000 ".

By method as above, optical pattern test section 141, detects light and shade pattern from signal of video signal, is overlapped in so as to detect The information of illumination light.Moreover, in the explanation, the example of the detection information from 1 pictures is illustrated, still, be overlapped in In the case that the information of illumination light is more, the situation of the detection information from multiple pictures is also had.

Moreover, for the value for detection information, the brightness value for the multiple pixels for being not limited only to judge in the R10 of region is put down Average or the dispersion value for judging the brightness value of multiple pixels in the R10 of region.Also, for the detection method of information It is not limited only to the method.For example, by calculating in the stipulated time, there occurs the quantity of the part of low brightness area, so that Can also detection information.

Then, other examples of the detection method of information having used ccd image sensor, being overlapped in illumination light are illustrated Son.

Here, illumination 50 is set to, straight pipe type fluorescent lamp, with as an example.Also, illumination 50, with the friendship of cycle T Voltage power supply is flowed, with as an example.That is, the low frequency illumination period of illumination 50 is T/2 seconds.Also, will shooting member The imaging sensor in part portion 112 is set to, ccd image sensor.

Ccd image sensor is configured to, and the reading of data is carried out in units of 1 pictures, therefore, in 1 pictures The time for exposure (electron exposure time) of each pixel is roughly the same.Therefore, in order to from signal of video signal detection information, and need more A picture.

Then, in order to using ccd image sensor detection straight pipe type fluorescent lamp irradiate illumination light change, and need by The electron exposure time is set at least less than 1/2 times of low frequency illumination period.Here, for the purpose of simplifying the description, by the electron exposure time It is set to low frequency illumination period 1/4 times of the T/8 seconds of T/2 seconds.

In the case, Figure 10 is shown, the luminance signal obtained in infomation detection processing by optical pattern test section 141 is shown The multiple pictures gone out.

Figure 10 is the figure for illustrating to detect the method for the information for being overlapped in illumination light using multiple pictures.

Figure 10 (a) is to show, the cycle is the figure of the change of the light quantity of the illumination light of T/2 seconds.

Figure 10 (b) is to show, the figure of a part for multiple pictures shown in the luminance signal obtained is handled by infomation detection. A part for the plurality of picture is picture P11, P12, P13, P14, P15.

Picture P11, P12, P13, P14, P15 are sequentially generated according to picture P11 to P15.That is, picture P15 is, The picture generated after picture P11.

Each of picture P11, P12, P13, P14, P15, it is corresponding with the time shaft of Figure 10 (a).

Here, optical pattern test section 141, will be rule with the light quantity of illumination light in picture P11, P12, P13, P14, P15 The corresponding picture in part more than definite value, is set as judging picture.Judging picture is, the picture for detection information.Here, will Picture P11, P12, P13, P14, P15 of Figure 10 (b), is set to picture when information is not overlapped in illumination light.

Here, odd number picture is set to judge picture, with as an example.That is, picture P11, P13, P15 are set to judge picture, with as an example.

In the case, each picture P11, P13, P15 are high brightness pictures.Here, high brightness picture refers to, forming should Judge the average value of the brightness value of multiple pixels of picture for the region of defined more than judgment threshold P.That is, high brightness Picture is the picture integrally to become clear.Here, judgment threshold P is, the threshold value for detection information.

Hereinafter, judgement picture for being averagely less than judgment threshold P of the brightness value for the multiple pixels for judging picture will be formed, Referred to as low-light level picture.

Figure 10 (c) is to show, the figure of each picture of information overlap when illumination light.

In information overlap in the case of illumination light, each judgement picture is high brightness picture or low-light level picture.Herein In the case of, multiple judgement pictures are shown, certain light and shade pattern.

Herein, it is contemplated that, high-brightness region is defined as " 0 ", low brightness area is defined as " 1 ".In the case, light figure Sample test section 141, by judging to form whether the average value of brightness value of each multiple pixels for judging picture is judgment threshold P More than, so as to detect " 0 ", " 1 ".

That is, optical pattern test section 141, by by the shape of each brightness value corresponding with each of multiple pictures State is detected as light and shade pattern, so as to detect the information for being overlapped in illumination light.Each brightness value is obtained from signal of video signal Value.That is, optical pattern test section 141, by detecting light and shade pattern from signal of video signal, illumination light is overlapped in so as to detect Information.

Herein, it is contemplated that, for example, the indication code " 100 " as configured information is overlapped in illumination light.In the case, as Picture P11, P13, the P15 for judging picture are respectively low-light level picture, high brightness picture and high brightness picture.

In the case, optical pattern test section 141, by judging to form the more of each judgement picture (for example, picture P11) Whether the average value of the brightness value of a pixel is higher than judgment threshold P, so as to detect indication code " 100 ".

Moreover, in the case where handling in an interleaved manner each picture, each picture is odd field or even field. As a result in units of field, detect to be overlapped in the information of illumination light.In the case, low frequency illumination period, believes than image The length of the cycle of each in number.That is, in the case, by making the cycle of each in signal of video signal, than low Frequency illumination period is short, so as to detect the information for being overlapped in illumination light.

Moreover, in the case where in a row by row fashion handling each picture, in units of frame, detect to be overlapped in photograph The information of Mingguang City.In the case, low frequency illumination period, the cycle than each frame in signal of video signal are long.That is, herein In the case of, it is shorter than low frequency illumination period by making the cycle of each frame in signal of video signal, it is overlapped in illumination so as to detect The information of light.

According to as above method, optical pattern test section 141, by detecting light and shade pattern from signal of video signal, so as to detect weight It is laminated on the information of illumination light.

Moreover, for the value for detection information, it is not limited only to form the brightness value of multiple pixels of each judgement picture Average value or for example form it is each judgement picture multiple pixels brightness value dispersion value.

Also, the detection method of information is not limited only to the method.For example, it is also possible to by calculating to go out at the appointed time The quantity of existing low-light level picture, so that detection information.

Method more than, using cmos image sensor or ccd image sensor, detection is overlapped in the letter of illumination light Breath.
